dc.description.abstractThe development of cement-less wastepaper-based lightweight block (CWLB) is another important step towards the production of eco-friendly building materials from wastepaper. This block which was designed to be used for non-load bearing/non-structural application was developed without the use of hydraulic cement. This study was conducted to optimize the mix composition of CWLB for the purpose of maximizing its compressive strength. This aim was achieved by employing the Taguchi statistical optimization technique in conjunction with laboratory experimentation. The result indicated that water/binder ratio had the most significant effect on the compressive strength of CWLB. The analysis of result establishes the CWLB specimen with optimal parameter to be that which was made from; 2.5 WPA/Sand ratio, 0.75 Water/binder ratio, and 3.5 Metric ton (i.e. 13.7MPa) compacting force. Also, the optimal CWLB displayed; an average compressive strength of 2.71MPa which indicated an increase of 402% compared to the 0.50MPa displayed by the worst parameter combination and an average density of 901.5kg/m3. The compressive strength and the density of the optimal CWLB was found to maximally satisfy the requirements for non-load bearing lightweight blocks. Considering the high amount (typically, 75%) of waste content in the composition of CWLB, it was reckoned as a viable eco-friendly lightweight block suitable for non-load bearing application. Future work will investigate other relevant properties of CWLB which include; Elastic modulus, water absorption, thermal conductivity, and reaction to fire. Key-Words: - Taguchi method, compressive
